photosynthesis
transcription
Glucose is broken down into pyruvic acid during which process
Each glucose (6C) produces how many pyruvic acid (3C) molecules?
5
2
3
4
What role do NADH and FADH2 (produced during Glycolysis and Kreb's Cycle) play in cellular respiration
they are energy carriers (hydrogen)that use that energy to produce massive amounts of ATP
They are waste products and are pushed out of the cell
They are necessary for long-term energy storage
They don't play any role in cellular respiration
What are the outputs of the kreb's cycle
CO2
H2O
ATP
NADH and FADH2
What happens in the electron transport chain?
NADH and FADH2 drop off hydrogens to form massive amounts of ATP
pyruvic acid is formed from breaking down glucose
CO2 is released and H2O and ATP
glucose is broken down and ATP is formed
Which step of aerobic cellular respiration makes the most ATP?
Glycolysis provides a cell with a net gain of
2 ATP
4 ATP
32 ATP
36 ATP
The Krebs cycle does NOT occur if
oxygen is present
oxygen is not present
glycolysis occurs
carbon dioxide is present
Aerobic cellular respiration uses 1 molecule of glucose to produce approximately
2 ATP molecules
4 ATP molecules
32-34 ATP molecules
36-38 ATP molecules
Lactic acid fermentation occurs in
bread dough
any environment containing oxygen
muscle cells
mitochondria
Most plants appear green because chlorophyll
does not absorb green light.
reflects violet light.
absorbs green light.
none of the above
If carbon dioxide is removed from a plant’s environment, what would you expect to happen to its production
of high-energy sugars?
More sugars will be produced.
No sugars will be produced.
The same number of sugars will be produced but without carbon dioxide.
Carbon dioxide does not affect the production of high-energy sugars in plants.
What role does NADPH play in cellular respiration
It is long term energy storage
it is a high-energy hydrogen carrier
it breaks down glucose
it is an enzyme
what are the inputs of the calvin cycle?
NADPH
ATP
CO2
H2O
chlorophyll
